The Diamondback Insight 1 Bike blends the best of the road and mountain worlds to provide a sleek, upright-riding bike. Not only is the Insight 1 perfect for commuting, training, and weekend rides, but you can also really kick up the performance level when so inspired. Its rock-solid foundation is a 6061-T6 butted aluminum frame with aero straight blade steel fork which delivers smooth, stable and precise handling. A Shimano 21-speed drivetrain can handle both flat roads and climbs with equal aplomb, plus the 7-speed EF trigger shifters make changing gears a breeze. Roll in comfort all day long perched on a gel saddle and ride with peace of mind knowing the Insight 1's linear pull brakes deliver some serious stopping power. And for maximum versatility, the 700x32c Kenda Kwick-Trax tires provide the means to take in both paved and dirt surfaces when you're out enjoying the great outdoors.

Bought the bike during Veteran Day's sale. Arrived in a week. Easy to assemble, but had to make some brake adjustment - nothing you cannot do after watching some Youtube video. So far, the bike rides very nicely and gear shift is precise and easy. I did need to add a kickstand.

Nashbar customer service is wonderful. As promised, they match their own advertised price within 30 days, I got refunded for price difference (22% vs 25% discount) and shipping. It is a wonderful deal. More than 100 dollars less than the cheapest model at a local bike shop with better components.

We have a fleet 0f these in a scout camp, all medium. We get an occasional adult or large youth so we felt the need to add a large. Our experience with the wheels has not been the best and we need to check them frequently for uneven tension.

I got bike delivered to friends house in Pittsburg assembled it and rode gap trail to DC. I liked everything about it except seat but I just used normal shorts and was riding some 60 mile days. The steel chain rings are more durable than alloy and the frame felt good handling responsive. The wide "gel" grips are nice to. A great bike for the money.

I was very excited to buy this bike. But excitement did not last long. Overall its a nice, light bike. I got flat tires twice and both times with just Twig. The tires are like paper made. Saddle is not comfortable for long ride. I ride roughly 20 miles a day, twice in a week. Brake lever are flimsy as well. And here is a bummer, right on 30th day of ordering (not delivery), prices got down ~$50 :(So this could be your good bike, if you spend some extra on buying good quality tires and saddle.
